HPI SX-12MGLP 7.4V Metal Geared Servo HPI-161067

The HPI SX-12MGLP Servo (7.4V/12kg/Metal Geared), part number HPI-161067, is a high-speed, low-profile digital servo for responsive radio-control steering. Its compact design helps keep weight and bulk to a minimum, while the brushless motor delivers rapid response for precise control. This makes it a suggested compatibility choice for 1/10-scale drift cars, where smooth transitions and quick counter-steering can help maintain a controlled drift angle. Titanium gears and metal bearings are designed to support dependable performance, and the case combines plastic and aluminium construction. The servo uses a 25T spline and operates across a broad 4.8V–8.4V range, allowing its speed and torque characteristics to change with the supplied voltage.

Performance And Construction

At 7.4V, the SX-12MGLP provides a 0.082-second transit speed over 60 degrees and 13kg-cm of torque. It remains suitable for different electrical setups, with specifications ranging from 10kg-cm at 4.8V to 14kg-cm at 8.4V. The low-profile format is useful where available installation space is limited, while the included servo horn is excluded from the stated 48g weight.
